Code protected purchase
So I have a client that is primarily an online college. They write their own curriculum and the students purchase the book in PDF form. Currently, they email the book to the student after the payment is received. We want to make it so that students can purchase the book from the website but only with a code that they student would receive once they're accepted.
Is there a way to have like a "purchase code" or something like that with the Duda ecommerce options?
